An outage of a cellular base station is detected by a neighboring base station when a beacon signal previously stored by the neighbor in respect of the base station being monitored is compared with the result of a subsequent search for that signal and found to have deteriorated or ceases to be detected. If the search identifies such an event, the search is repeated at a shorter interval and an outage is reported to a management center if the base station also fails to be detected on subsequent consecutive sampling cycles. This avoids false alarms from reboots and other transitory losses of signal that would be caused by an outage report based on a single loss of signal. |

Consolidated processing of storage-array commands by a snapshot-control media agent
A “snapshot-control media agent” (“snap-MA”) is configured on a secondary storage computing device that operates apart from client computing devices. A “forwarder” media agent operates on each client computing device that uses a storage array, yet lacks command channels to the storage array.

Efficient forwarding of encrypted TCP retransmissions
A network device receives TCP segments of a flow via a first SSL session and transmits TCP segments via a second SSL session.

The behavior-based SS7 filter also can determine whether the behavior of the SS7 traffic fits within a tolerance threshold of the behavior profile. If the SS7 traffic fits within the tolerance threshold, the behavior-based SS7 filter can instruct a signal transfer point (“STP”) to which the SS7 traffic is directed to allow routing of the SS7 traffic. If, however, the SS7 traffic does not fit within the tolerance threshold, the behavior-based SS7 filter can instruct the STP to deny routing of the SS7 traffic. |

Pseudo frequency division multiplexing
An optical transmitter is operable to generate an optical signal by modulating a number N of frequency divisional multiplexing (FDM) subcarriers using transformed digital signals which are determined by applying a pseudo FDM (pFDM) transformation to preliminary digital signals representative of multi-bit symbols. Rather than experiencing the effects of the number N of FDM channels, the optical signal experiences the effects of a different number M of pFDM channels, where M≠N. In some examples, the number M of pFDM channels is less than the number N of FDM channels, and frequency-dependent degradations may be averaged across different symbol streams. In other examples, the number M of pFDM channels is greater than the number N of FDM channels, and different symbol streams may experience different frequency-dependent degradations. An optical receiver is operable to apply an inverse pFDM transformation in order to recover estimates of the multi-bit symbols. |

Passive islanding-to-grid-connected switch method
The present invention discloses a passive islanding to grid-connection switching method for a VSC HVDC transmission system. When the VSC HVDC transmission system in an island operation state, whether the VSC HVDC transmission system enters an grid-connection state is determined by detecting whether an overcurrent phenomenon has occurred in a converter valve-side three-phase alternating-current or a converter bridge arm current, and detecting a change status of an alternating-current side voltage. The system is controlled to switch from an island operation control mode to a grid-connection control mode. At a moment of switching, the online control mode is smoothly switched to by changing a power instruction and performing phase tracking on a current grid voltage, so that continuous operation of the system is maintained. |

Electric power grid supply and load prediction using cleansed time series data
An apparatus includes a processor to: assign each value of each set of values of an initial supply meter data and of an initial load meter data to one of multiple buckets based on weather conditions and/or time and date; for each bucket, generate upper and lower bounds of power provision and power consumption values, and use the upper and lower bounds to identify outlier values assigned to the bucket; for each set of values within the initial supply meter data and within the initial load meter data, generate a naive model from the non-outlier values, and use interpolation and the naive model to fill in gaps, thereby generating cleansed supply meter data and cleansed load meter data; and store the cleansed supply meter data and cleansed load meter data together as merged meter data for use in making predictions. |

Inrush control with multiple switches
A novel system is offered for supplying power from an input node to a load coupled to an output node. The system may have multiple switches coupled between the input node and the output node. One or more limiting circuits may be configured for controlling the switches so as to limit outputs of the switches. For example, the limiting circuits may limit current through the respective switches. One or more timers may set a delay period for indicating a fault condition after the limiting is initiated. |

Compressor protection and grid fault detection device
A method for monitoring a compressor includes measuring a power factor of a motor of a compressor. The method includes selectively detecting an occurrence of a fault event of an electrical grid based on the power factor. The method includes, in response to detecting that the fault event has occurred, switching the compressor from a first state to a second state. The compressor consumes less power in the second state than in the first state. The method includes identifying an apparent conclusion of the fault event. The method includes, in response to the apparent conclusion of the fault event, waiting for a first delay period before switching the motor of the compressor back to the first state. |

Ground electrode pad for spark plug
A spark plug ground electrode assembly including a ground electrode having a ground electrode base defining a receptacle. A base flange extends about less than an entirety of the receptacle to define an open lateral end of the receptacle. The open lateral end of the receptacle is arranged to receive a ground electrode pad slid into the receptacle and onto a support surface in a direction perpendicular to a spark plug longitudinal axis. The flange of the ground electrode pad is arranged between the base flange and the support surface to restrict movement of the ground electrode pad along the spark plug longitudinal axis. A welding is at the open end of the receptacle to restrict movement of the ground electrode pad in the direction perpendicular to the spark plug longitudinal axis. |
